Development: At birth, only maxillary, sphenoid, and ethmoid sinuses are present.Frontal sinuses develop from cranial extension of ethmoid cells at 5 years old, reaching full size by 19 years.Maxillary sinuses expand to reach the nasal floor level by 8 years, reaching full size by 16 years.Sphenoid sinuses extend posteriorly over the first 7 years, reaching completion by 15 years.
Anatomy of the head and neck

The maxillary sinuses are large pyramidal cavities within the maxillae. Their floor is formed by the alveolar part of the maxilla, with the roots of the maxillary teeth, particularly the first two molars, creating conical elevations (Figure 1.1).

Surgical treatment remains the preferred option. For maxillary sinus tumors a radical maxillectomy is usually the minimum required. Orbital invasion may necessitate orbital exenteration. Tumors of the ethmoid sinus frequently involve the orbit, and the ipsilateral eye may have to be sacrificed. Extension superiorly into the anterior cranial fossa may necessitate craniofacial surgery. Sphenoid and frontal sinus tumors tend to present late, and surgery has little to offer due to the close anatomical proximity of crucial neurovascular structures.

The causes and pathogenic mechanisms underlying odontogenic sinusitis (OS) include direct bacterial infections of the maxillary sinus mucosa arising from apical or marginal periodontitis [1–3]. Extraction of the causative tooth is reasonable because, in the long term, treatment of the causative tooth is essential to eliminate the source of infection. However, there has been no consensus regarding the preservation or extraction of the causative tooth [4,5], and several dental treatments for OS, including tooth extraction, root canal treatment (RCT), and apicoectomy, have been reported [6]. This prospective study aimed to statistically analyse the cure rates of OS and the contributing factors of cure after a stand-alone treatment with a tooth extraction in patients diagnosed with OS and indicated for causative tooth extraction.

Table 3 shows the outcomes in the affected teeth. All the patients achieved an ODS cure. The median time to symptoms resolution and completion of re-epithelialization of maxillary sinus was two months (range 1–7, interquartile range 1.5–2). The two patients with mobility in the affected tooth declined tooth extraction. Contrary to expectation, after ESS these patients achieved immobility in the affected tooth and were able to preserve the tooth for an observation period of six and seven months, respectively. Of the 35 patients with immobility in the affected tooth, 4 without a root canal and 15 with a previous root canal underwent only ESS for personal reasons. Within the median observation period of 12.5 months (range 1.5–24, interquartile range 6–18.75), none of the patients with ESS with a root canal or a re-root canal treatment required tooth extraction. Two patients with only ESS required tooth extraction; in one instance because of a tooth fracture six months after the ESS, and in the other instance because tooth pain and granuloma of the maxillary sinus persisted for five months after the ESS. Among the 35 patients with immobility in the affected tooth, only 1 required tooth extraction for a complete ODS cure in the median observation period of 11 months (range 1–58, interquartile range 4–19).
Bilateral orbital granulomatosis with polyangiitis complicated by central serous chorioretinopathy

Given concern for orbital cellulitis, the patient was empirically initiated on systemic IV ampicillin-sulbactam pending further investigations. Gadolinium-enhanced magnetic resonance imaging revealed a 3.2 × 2.5 x 2.5 cm heterogeneously enhancing lesion in the left superolateral orbit, involving the lacrimal gland, with associated globe deformity and enhancement of the superior and lateral rectus muscles and adjacent preseptal and orbital soft tissues (Figure 1D). In addition, the right lacrimal gland was noted to have mild enlargement and heterogeneity. Computed tomography imaging of the orbits with intravenous contrast demonstrated the aforementioned orbital lesion without associated bony dehiscence or lytic changes. Mild mucosal thickening of bilateral maxillary sinuses was further noted.
